Effect of Placement of Scattering Generator Locations on Microgrid Testbed Systems

The location of the plant depends on the potential of renewable energy sources. This microgrid power source is a renewable energy generator that will be optimized. The mobile power plant in which implemented is a synchronous generator coupled with a diesel engine, and two power plants based on an induction generator which is implemented as a wind power plant and a micro hydropower plant. Generator will be operated in stand-alone and parallel in the system when the load increases, the load decreases. The increase in load and decrease in the burden can be influenced in terms of the location of these renewable energy plants and can cause a decrease in voltage and frequency. To support the benefits of the scattered power plant, good planning is needed, including determining the location of placement and the power of the scattered power plant that is used so that by optimizing the location of the power plant system in order to achieve optimal operating patterns, when the system voltage stability can reach the voltage parameter 380 V (+ 5% and -10%) and 50 Hz (± 1%) frequency when the generator is working in parallel with variations in loading. Voltage reduction can be minimized by choosing the cable type and generator distance.
